I'm currently using impserve - which is great. However, when I went to transfer books to my reader today, my reader and impserve are not seeing each other - the driver icon is not showing as being connected. I uninstalled/reinstalled the driver - but still no luck.

You really need the driver icon in the system tray to "activate" prior to using Impserve. It looks like an "eiffel tower" or a tree with branches when activated/connected/on.

If you go to your Control Panel, and double-click the System icon, then tap the Hardware tab, you will see a button labelled Device Manager. Click that, expand the Universal Serial Bus controllers entry and you should see that ebook item when your EBW1150 is connected (see "-pic1" below)

If you see that ebook item, then double-click it to see the Properties and tap the Driver tab (it should then look like "-pic2", below). Ensure you have the right driver, if not, click the Update Driver button. You may also want to tap the Driver Details button to ensure you have the info as in "-pic3" below.

However, if on that ebook item you notice a yellow exclamation point, then you must Uninstall the driver and then, WITHOUT the EBW1150 being connected, re-installed the ETI usb driver v3.00. Then when done, connect the EBW1150 and see if it works.

If it didn't work, then can you install the ETI usb drvier v3.00 on another computer and verify that the EBW1150 and usb cable are functional? If not, you may need warranty service.

Thank you so much for your help. I installed/reinstalled the driver 2 more times - with no luck - still no signal. I had checked the device driver before - and, again, it showed no problems. I took your advice and installed the driver and impserve on another computer - and the device worked fine - which narrowed the issue down to it being a problem with my laptop. I finally tracked the problem down to a firewall issue (which made no sense, because the driver only stopped working recently and the firewall has always been there) - but when I shut the firewall down and then reinstalled the driver and impserve, and then restarted the firewall, the driver worked. So, the problem is solved - I guess....

You're quite welcome!

I have heard about that firewall problem before, though I too think it makes no sense. However, the usb connection does use the "http protocol" with Impserve, so maybe that's where the firewall "protection" kicked in.
